Embodiment

[0027] Refer to Figure 1 、 Figure 2 、 Figure 3 、Figure 4 , Figure 5 and Figure 6 , a low-voltage AC fixed switchgear, comprising a box body 1, an air inlet box 5 fixedly connected to the inner wall of the box body 1, and an air exhaust box 6 also fixedly connected to the inner wall of the box body 1. Air enters from the air inlet box 5 and is discharged from the air exhaust box 6. It further includes:

[0028] Mounting blocks 13, fixedly connected to the inner wall of the box body 1 and symmetrically distributed. The top wall of the mounting blocks 13 is fixedly connected with electrical devices 14, and the electrical devices 14 are supported and installed by the mounting blocks 13;

[0029] A heat conduction and heat dissipation component, which includes a second conical body 9 fixedly connected to the outer wall of the air exhaust box 6, and the second conical body 9 is fixedly connected to the inner wall of the box body 1. The inner wall of the second conical body 9 is fixedly connected with heat dissipation fins 20. One end of the heat dissipation fins 20 far from the second conical body 9 is fixedly connected with a heat conduction rod 19, and one end of the heat conduction rod 19 far from the heat dissipation fins 20 is fixedly connected with a heat conduction plate 15. The outer wall of the heat conduction plate 15 abuts against the outer wall of the electrical device 14. The heat conduction plate 15 fully contacts the electrical device 14, and the heat is conducted to the heat dissipation fins 20 through the heat conduction rod 19, facilitating subsequent heat dissipation operations;

[0030] A first conical body 8, fixedly connected to the top wall of the air inlet box 5. The inner wall of the first conical body 8 is fixedly connected with a cross-shaped air guide frame 16, which divides and diffuses the air extraction through the cross-shaped air guide frame 16, facilitating the air extraction to fully contact and carry the heat on the electrical device 14 for heat dissipation;

[0031] A moisture-proof detachable component, arranged on the inner walls of the air inlet box 5 and the air exhaust box 6.

[0032] Referring to Figure 3 and Figure 5 , the moisture-proof detachable component includes a drying box 10 slidably connected to the inner walls of the air inlet box 5 and the air exhaust box 6. Symmetrically distributed and uniformly arranged placing ventilation holes 11 are opened on the outer wall of the drying box 10, which are used for ventilation to facilitate the air extraction to pass through and for adding drying balls. A pulling ring 12 is fixedly connected to the outer wall of the drying box 10. The water molecules in the air extraction will pass through the placing ventilation holes 11 of the drying box 10 and be absorbed by the drying balls in the drying box 10. The drying box 10 can be pulled out of the air exhaust box 6 or the air inlet box 5 through the pulling ring 12, facilitating the addition of drying balls.

[0033] Referring to Figure 3 and Figure 6 , square frames 17 are fixedly connected to the inner walls of both the air inlet box 5 and the air exhaust box 6 and are symmetrically distributed. Electric fans 18 are fixedly connected to the inner walls of the square frames 17. The electric fans 18 can quickly form air extraction. Due to the structure between the first conical body 8 and the second conical body 9, the flow of air can be concentrated, so the electric fans 18 do not need too high power.

[0034] Reference Figure 1 As shown in Figure 1 , a door 2 is rotatably connected to the outer wall of the box body 1. A door handle 3 is fixedly connected to the outer wall of the door 2, and an observation window 4 is fixedly connected to the inner wall of the door 2. Through the observation window 4, the internal situation can be conveniently observed, and the door 2 can be opened through the door handle 3 for the maintenance and replacement of internal equipment.

[0035] Reference Figure 2 and Figure 3 As shown in Figure 2 and Figure 3 , dust-proof plates 7 are slidably connected to the inner walls of the air inlet box 5 and the air exhaust box 6. The dust in the air is filtered by the dust-proof plates 7 to prevent the electrical device 14 from being affected by excessive dust deposition and affecting normal use.

[0036] Specifically, when this AC low-voltage fixed-type switchgear is working / being used: First, the electric fan 18 operates to form suction. The air enters the first cone 8 through the air inlet box 5 at the bottom and is divided by the cross-shaped air guide frame 16 to make the wind more diffused, and then blows towards the electrical device 14. Since the second cone 9 of the first cone 8 and the second cone 9 is the only air outlet, the wind will move into the air exhaust box 6 through the second cone 9. When the suction passes through the air inlet box 5, it will be dust-proofed by the dust-proof plate 7. Then, the water molecules in the suction will pass through the placement ventilation holes 11 of the drying box 10 and be absorbed by the drying balls in the drying box 10. The drying box 10 can be pulled out of the air inlet box 5 or the air exhaust box 6 by pulling the pulling ring 12, which is convenient for adding drying balls. The drying balls are placed through the placement ventilation holes 11. Most of the heat of the electrical device 14 will be transferred to the heat conduction rod 19 through the heat conduction plate 15 and finally conducted to the heat dissipation fins 20. The heat dissipation fins 20 are arranged at the only place where the suction passes through. The suction will carry the heat on the heat dissipation fins 20 and flow into the air exhaust box 6. At this time, the remaining water molecules will be absorbed by the drying balls located inside the air exhaust box 6 to prevent the water molecules from condensing and flowing back. Finally, the heat is discharged from the air outlet of the air exhaust box 6.

[0037] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
